The word RFID refers to Radio Frequency Identification. RFID is a tracking system which uses intelligent bar codes to track items in a store. RFID finds many applications including Access management, tracking goods, Tracing human beings and animals, Toll collection, Non contact payment etc. Radio-frequency identification (RFID) based access-control system allows only authorized persons to enter a particular area of an establishment.
This kit is an effort to designing a prototype billing system based on RF ID to directly know the object and check out all the objects automatically to bill whole purchase by any user based on the RF ID. The object will have the unique ID tag installed. This tag will receive by the RF ID reader and sent to the PC. PC have the stored parameters of the item like cost, product. Once the object is identified the billing can be done easily. The bill will be stored in the PC. The billing process etc will be handled using PC interface.
RF ID is attached with each item. As soon as any item is taken nearby, the reader senses the ID of the item and sends data to the microcontroller. The microcontroller, in response sends this data to the computer. Hence all billing is done as per the data stored in the computers database automatically.
